Abstract:
The present study was done to evaluate a flock comprising of 300 Deccani lambs maintained at Livestock Research Station, Mahabubnagar, Telangana State for various genetic and non-genetic factors on certain biometrical measurements. Biometric traits pertaining to Rump Height (RH), Chest Depth (CD), Chest Width (CW), Hip width (HW), Fore-cannon bone length (CB) and Thigh circumference (TC) were included in this study. The data was recorded at birth, 15, 30, 45, 60, 75, 90,180, 270 and 360 days of age. On RH significant effect of sex of lamb was seen only at 45, 75 and 90 days age; that of season of birth at all ages studied while the effect of ewe weight was significant only during 180, 270 and 360 days. On CD the sex of the lamb significantly influenced during all the pre-weaning ages but not during post-weaning stages; Significant influence of season of birth was observed at 0, 30, 180, 270 and 360 days; ewe weight at post weaning and that of parity at 75 and 90 days was observed. On CW significant effect of sex of lamb was observed at 15, 30, 45, 60, 75, 180, 270 and 360 days age and that of season of birth of lamb at 15, 30, 45, 180, 270 and 360 days. In the case of FC significant influence of sex of lamb was observed at 0, 15, 30, 45, 60, 75 and 360 days while the influence of season of birth and weight of ewe was significant at 180 days only. Significant effect of sex of lamb on HW was seen at all the studied ages. In the case of TC effect of sex was significantly evident on 30, 45 and 60 days while the effect of season of birth and ewe weight was evident on 180, 270 and 360 days.
